Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0054] Such as figure 1 As shown, a step-by-step optimization method for medium- and long-term power safety correction includes the following steps:

[0055] Step 1. Collect the information required for medium and long-term power safety calibration.

[0056] Determine the dispatch cycle that needs to carry out medium- and long-term power safety corrections, obtain the load and backup demand at each time period in the dispatch cycle, obtain the maintenance plan and contact line plan in the dispatch cycle, and obtain the power plan of each power plant. The above information is medium- and long-term power safety Correction required information.

[0057] Step 2. Based on the collected information...

Abstract

The invention discloses a step-by-step optimization method for medium and long term electric quantity safety correction. The method comprises the following steps of collecting information required bymedium and long term electric quantity safety correction; based on the collected information, establishing a power flow checking optimization model for medium and long term electric quantity safety correction by taking the minimum power flow out-of-limit amount of the power transmission section as an objective function; calculating a power flow checking optimization model, and judging whether theelectric quantity plan meets power grid safe operation requirements or not according to a power flow checking optimization result; and in response to the condition that the electric quantity plan doesnot meet the safe operation requirement of the power grid, establishing an electric quantity plan optimization model for medium-and-long-term electric quantity safety correction by taking the minimumadjustment of the starting and stopping states of all generator sets as an objective function, and correcting the electric quantity plan. Compared with traditional experience correction, the method greatly improves the refinement level of power grid dispatching, and provides technical support for increasingly complex trans-provincial and intra-provincial dispatching plan compilation.

Description

technical field [0001] The invention relates to a step-by-step optimization method and system for medium- and long-term power safety correction, and belongs to the technical field of power system scheduling automation. Background technique [0002] With the rapid development of new energy, new energy and load centers have the characteristics of reverse distribution, which need to be consumed within the province and across provinces, and the electricity traded across provinces is growing rapidly. Electricity market-oriented reform continues to advance, and various provinces actively organize various electricity market transactions. The medium and long-term transaction types gradually increase, the proportion of transaction electricity gradually increases, market transaction electricity gradually replaces annual planned electricity, and planned electricity and market electricity coexist. [0003] The main feature of the medium and long-term market is the transaction in the for...
